美国：1950年 Margaret De Patta Studio Jewelry
关于 Margaret De Patta 的介绍，我这里将鉴赏者的英文对话贴出，对于文中所提到“建构主义艺术“ 结合 Margaret De Patta 首饰的设计风格，超出了我的理解能力。如果哪位网友读到此文，希望能够帮助补充这段对话的译文。
These are examples of a rebel. Margaret De Patta was a rebel in many ways. These were American studio jewelers. They were mid-century modernists. They were rebelling against the type of jewelry that was mass-produced. What they wanted to do was to deconstruct things and to make things sharp and clean.
And they used, not diamonds and gold and precious metals; they might have used sterling and some stones and some wood. And they were not for the masses. They were for the intellectual elite.
And there was a group on the East Coast and there was a group on the West Coast. Now, Margaret De Patta was the leader of the West Coast group.
She started making jewelry in the '30s and opened her workshop in 1935. But she didn't just design. She was actually hands-on. She made this jewelry herself, and she well marked it.
Her technique was called constructivism. She just pared it down to the essence of what jewelry should be.
Now, what we have here are iconic examples of her work. Very, very good, strong, clean lines. She used interesting stones. Right here we have rutilated quartz, and she favored sterling. On this piece down here, which is a matching pin and earring set, she's used ebony, which is a dark wood. The white material is chalcedony, which is an agate, and freshwater pearls.
